Dried in. The term we use for having gotten the roof covered and typically the windows and doors in. In this case, we have made good progress on this custom home in Sagle. It features over 2000 SQF of living space, a 500 SQF attached garage, a 288 SQF bonus room above the garage and a 192 SQF covered front porch. Our own roofing crew meticulously roofed this 4900 SQF roof, which features 12/12 pitches, 10/12 pitches and 4/12 pitches. A lot of variety. We used Certainteed Landmark series asphalt shingle roofing, as picked by the homeowner. When roofing, we pay particular attention to the details. First, we designed the home with a 14" raised energy heel. That means we can get a full R50 insulation at the eaves and maintain a 2" attic ventilation channel. The R50 and the airspace will help eliminate ice dams. Then, we use ice and water shield on the first 6 feet of roof deck, essentially using ice and water shield to 3' inside the building envelope. This eliminates leaks if there are ice dams. An ice dam is when snow melts over the heated portion of the house and then refreezes over the eaves. Melting snow behind it can get caught behind this ice dam and back up under the shingles. Ice and water shield seals around the roofing nails and laps over the drip edge, so that if water did get beneath the shingles, it will not see wood but will be shed on this secondary layer out over the eave's drip edge. But again, this house likely won't see ice dams because of the R50 insulation, preventing heat loss through the roof. The steep pitches help as well. The valleys are also another ice dam prone area, so we use ice and water shield the length of the valleys. And, we have seen other builders have call backs for leaks due to ice dams over porches, so we covered the entire roof over the porch with ice and water shield. We also liberally used the shield on the entire 4/12 plane where a 12/12 plane intersects in a valley. We hold all nails 8" back from all valleys. At the roof to wall intersections, we also use ice and water shield behind the step flashing and keep our nails back from the sidewall 4", not penetrating the step flashing. The step flashing only gets nailed to the sidewall. It is cheap insurance. We have never had a roofing callback, and we sleep peacefully at night having paid attention to the details. We also do what some other contractors don't do - we clean up after ourselves, including cut pieces on the roof, the rubber bands from our nail coils and the scraps on the ground. We also make sure to never traffic on the shingles, especially on warm days, which would tear them up and cause premature wear. When picking a roofing contractor, pick one that pays attention to these details.
